APPENDIX. 



A. GENERAL. 



The animals and plants employed in this work should be 

 obtained alive, and if possible by the student himself. Direc- 

 tions for killing and preserving them will be found under each 

 head. Living specimens should be kept ready at hand, in order 

 that their habits and movements may be studied side by side 

 with their structure. 



Apparatus required. 



I. Dissecting instruments, as under 



Two or three scalpels of variable sizes, with straight 

 blades. 



Two pairs of scissors with straight points (one large and 

 one small). 



Two pairs of forceps (one large and one small) with 

 straight points, the inner faces of which shall be ground 

 or notched. 



A seeker with a tapering point. 



A German-silver blow-pipe. 



Two razors (for section-cutting). 



A section-lifter. This may most readily be made by 

 beating out the terminal ^th of a piece of copper-wire, 

 4 inches in length. 



3 or 4 camel's hair brushes. 



6 needles mounted in long wooden handles.
